Welcome to the project pages of Simple and Fast Implementation of Exact Optimization Algorithms with SCIL. This project is part of the DFG Priority Programme Algorithm Engineering (SPP 1307).

SCIL

The SCIL (Symbolic Constraints in Integer Linear-Programming) software package facilitates and accelerates the implementation of exact solution algorithms for hard optimization problems. It has been applied successfully in many different areas. SCIL is based on an efficient branch-and-cut algorithm. However, in contrast to other software, it allows to specify symbolic constraints instead of linear constraints. Symbolic constraints play an important role in Constraint Programming and make SCIL a user-friendly tool, allowing even non-experts to easily access powerful state-of-the-art optimization techniques.

Objectives

The overall objective of our project is to extend and improve the performance of SCIL significantly. The two main improvements will concern the implementation of new symbolic constraints and numerically exact solution methods. Among others, we will introduce symbolic constraints modeling nonlinearity both in the objective functions and in the side constraints. This will drastically extend the range of problems to which SCIL can be applied directly. The implementation of a numerically exact solver is not only desirable in general, but can be crucial in safety-critical applications, such as automatic verification of hybrid systems.
